Abstract

This paper describes the basic principles of wireless power transfer technology based on magnetic field resonance. In addition, we introduce applications including the LED TV, OLEV, and HH-RM CCC Charger. In order to demonstrate the advantages of the coil structure with the ferrimagnetic material and metallic shielding, magnetic field distributions and the electrical performance of three different coil structures were investigated via 3D electromagnetic (EM) field solver and SPICE simulation. In addition, EMF and electromagnetic field radiation were measured and analyzed.
